Abstract
L'invention concerne une unité capteur optique, un appareil d'enregistrement/reproduction de données, un procédé de commande et un support d'enregistrement. L'unité capteur optique et l'appareil d'enregistrement/reproduction comprennent chacun une lentille à champ proche et font appel à une lentille à réfraction élevée de forme conique en vue d'une utilisation efficace du champ proche. Deux unités lentilles doivent être compatibles avec un support d'enregistrement classique. L'unité lentille est conçue en fonction d'une distance entre le support d'enregistrement et la lentille, et l'inclinaison ou la vibration des unités lentilles est régulée.
